LEOPOLD KACZANDER, OF NEW YORK, N. Y., ASSIGNOR TO THE NATHAN MANUFACTURING COMPANY, OF SAME PLACE.

LUBRICATOR.

` SPECIFICATION forming part of Letters Patent No. 357,931, dated February 15l 1887.

Application filed October 21, 1886. Serial No. 216,854. (No model.)

.To all whom t may concern.:

Be it known that I, LEOPOLD KACZANDER, of the city, county, and State of New York, have invented certain new and useful Improvements in Lubricators, of which the following is a specification My invention relates to that class of lubricators (designed more particularly for use on locomotives) in which the oil-chamberis combined with a condensing-chamber in which steam is condensed, and from which the resulting water of condensation is caused to pass gradually to the oil-chamber, for the purpose of effecting the feed of the lubricant.

More particularly, my invention is an improvement on that kind of lubricator of which the one set forth in Letters Patent of the United States No. 179,226, granted to Nicholas Seibert, of June 27, 1876, may be considered the type; and its object is to reduce the cost of construction, to facilitate the process of manufacture, and to secure a device of increased simplicity, effectiveness, and convenience. In this connection I would state that 2 5 my lubricator is intended to be a double onethat is to say, one in which the same oil-cham-v ber serves to lubricate both cylinders of a locomotiveengine; and it is with this end in view that my improvements have mainly been 3o designed. I remark here, however, that some of said improvements are equally applicable to a single lubricator, or one which feeds only a single cylinder or other part.

In the accompanying drawings I have repre- 5 sented a lubricator which embodies the several features of my invention in their preferred form, and to these drawings I shall now refer in order to explain more clearly the nature of the invention and the manner in which 4o the same is or may be carried into effect.

Figure l is a vertical central section of the lubricator on line l 1, Fig. 3. Fig. 2 is a like section on line 2 2, Fig. 3. Fig. 3 is a hori zontal section on line 3 3, Fig. l, omitting the sight-feed tubes and their connections and the oil-gage. Fig. 4 is a section on line 4. 4, Fig. l, of one of the upper sight-feed-tube connections, omitting the hand-oiler. Fig. 5 is a y section of the same sight-feed-tube connection,

together with the hand-oiler, on line 5 5, Fig.

3,. Fig. 6 is a side elevation of the complete lubricator, together with its boiler connections. y

I shall first give a general description of the lubricator, and then point out the features which are of my invention.

A is the oil-reservoir. B5 is the condenser surmounting said reservoir and communicating with the same by the passages w to2 w, through which the water of condensation (as 6o permitted by the valve w) passes from the condenser to the lower part of the oil-reservoir.

S is the main steampipe leading from the boiler (see Fig. 6) to the top of the condenser, where it connects with the neck c. V 6 5 S is the steam-valve for the pipe S.

Vithin the condenser are two independent pipes, p and p', which extend up ncarly to the top of the condenser, and at their upper ends are provided with openings for the entrance 7o of Vsteam from the condenser. Each pipe screws into the bottom of the condenser-that is to say, into the top of the oil-reservoirand there communicates with a passage, s or top of the oil-reservoir are entirely distinct and separate and have no communication with each other. rlhe one s leads to the upper sightfeed connection, B, and the other, s', leads to the upper sightfeed connection, B. Each of 8o these connections is like the other, so that a description of one will answer for both.

Referring to the connection shown in sec tion in Figs. 4t and 5, it is provided with a horizontal passage, ai a, from its inlet to its exit, where is located the oil-exit pipe c, and with a screwvalve, B2, which controls the opening through which the ascending oil passes from the sight-feed tube on its way to the pipe c2. This valve is neither a throt- 9o tling nor a regulating valve, but is simply a shut-off valve, its only and exclusive function being to prevent the escape of steam from the passage s or s', or fromeither of the pipes c, through the sight-feed glass or tube in case the latter shouldbreak. In other words,it is a mere safety appliance, which does not influence the normal working of the lubricator, and whether open (as represented in Fig. l) or closed, (as represented in Fig. 5.) or, in fact, Ico in any position, it does not interfere with free communication between the two portions n s. These passages which are formed in the 75 a of the horizontal passage, this being due to the fact that the plug on its end,which, when screwed down, stops the Lipper opening of the sight-feed tube, is not ofasize to fill the passage between n2 and a. rIhe connection is also provided with a lateral extension-neck, n3, designed to receive a common stationary handoiler, H, of Well-known construction, provided with an oil-cup, h, and a regulating-valve, h'. The neck n3 communicates by an independent passage, n', with the oil discharge or exit pipe c".

With each upper sight-feed connection, B or B, is combined a lower sight-feed connection, B3, having the usual feed-nozzle,f, and regulating-valve R.

K is the sight-feed tube intermediate between the two connections.

On the bottom of the oil-reservoir is the single cross-channel O', which connects the two lower sight-feed connections, and into this channel enters the lower end of the oil-feed pipe 0, which leads from the upper part of the oil-chamber F is thetilling-plug.

WV is the drain-cock.

G is the indicator commonly employed to show the amount of oil in the oil reservoir.

The operation of the lubricator is as follows: Opening the steam-valve S', steam from the boiler enters the condenser, and the water of condensation resulting therefrom is led by passages w w2 w3 to the bottom of the oil-reservoir. The displaced oil passes over into the pipe 0 at its top and is led into the single straight cross-channel O,whence it is distributed to both of the lower sight-feed connections. The oil passing the feed-valves R and nozzlesf ascends, drop by drop, through the water in the visible-feed tubes, and nally passes out through passages n into the discharge-pipes ci, which connect with the parts to be lubricated. I remark he-re that when steam is turned on it passes through the parts p s andp s,and by its condensation fills the sightfeed tubes with Water. At the same time that the oil is fed, as above described, jets of steam pass from the condenser through the passages p s n2 a and p s at n into the discharge-pipes, exerting a balancing pressure directly on top ofthe oil in the sight-feed glasses, so that the oil is pressed through the passages a simply by the weight of the water-column in w wt w3 and the condenser.

I have already called attention to the fact that the steam conduits or passages s s are separate and distinct from each other and have no connection whatever with each other save such communication as may be afforded by way of the condenser, into which both of the pipes p p open. This I deem to be avaluable feature of my improvements, because by this arrangement the two sides of the lubricator can act independently of each other, which would not be the case were such passages arranged (as has been heretofore suggested by others) to directly communicate with each other. It will also be seen that by reason of the cross-channel O, I am enabled to employ only one oilpipe for the distribution of oil to the opposite sides of thelubricator, which greatly simplifies the construction.

In the normal operation of the lubricator the valves B2 are of course wide open, as shown in Fig. l; but if one of the sight-feed glasses should break then the valve B2 appertaining to the broken glass should be closed, as shown in Fig. 5, thus closing communication between the glass and both the conduits s or s', as the case may be, on the one hand, and the glass and the discharge-pipe c2 on the other hand, but at the same time leaving open communication between s or s and c2. Under these conditions (the sight-feedbeing disabled) I can make use of the hand -oiler for lubricating purposes, as follows, it being of course understood that it can only be used when steam is shut off from the cylinders, as it is, for instance, when the engine is going downgrade:

I ll the cup with oil, and then upon opening the valve It' oil will dow through the eX- tension-neck a3 and by-passagea into the discharge-pipe e2. Then I close the Valve 7L and open steam-valve S for a moment, which will send ajet of steam, through p s or p s', as the case may be, and a2 a, into the discharge-pipe, carrying the oil from the hand-oiler along with it. In this way it is feasible to use a steam- `jet in connection with the hand-oiler, and this I deem a feature of value, which is applicable to either a double or a single lubricator.

In conclusion I state that I am aware that in various modifications of the lubricating apparatus of which thepatented Seibert lubricator, hereinbefore referred to, is the type, the lubricators have been constructed with auxiliary steam-jets wholly or partially within the connes of the body of the lubricator; and I am also aware thatlubricators in combination with hand-Oilers have been made before. I claim none of these features, broadly.

I am also aware that the auxiliary steamconduit has been so constructed and arranged that it will discharge its jet of steam into the passage leading to the oil-exit at a point beyond the upper end of the visible-feed tube and between the latter and the oil-exit. In my improved lubricator, on the contrary, the auxiliary steam-conduit is so arranged that the steam passing therefrom to the oil-exit is discharged directly over the open top of the visible sight glass or tube, producing a very efficient balancing action.

Having now described my improvements and the preferred way of carrying the same into effect, what I claim, and desire to secure by Letters Patent, is

l. The combination of the oil-reservoir, the condenser, the two sight-feed tubes and their connections, the two oil-exit pipes, and auX- iliary conduits leading from the condenser to the upper sight-feed connections for discharging steam into the oil-exits directly over the upper ends of the visible-feed tubes, the parts ICO IIO

IZO

being so arranged that the upper ends of the si ght-feed tubes are between the oil-exit pipes and the discharge ends of the auxiliary steamconduits, substantially as and for the purposes hereinbefore set forth.

2. The combination of the oilreservoir, the condenser, the two visible-feed tubes and their connections, the oil-exit pipes, and two separate and independent auxiliary steam-conduits having no communication with each other and discharging steam from the condenser each into its appropriate oil-exit pipe, substantially as and for the purposes hereinbefore set forth. 3. The combination of the oil-reservoir, the condenser, the two visible-feed tubes and their connections, the two separate and independent auxiliary steam-conduits connected each with its appropriate upper sight-feed connection, the oil-pipe O, and the single cross-channel O', through which oil is supplied to both of the lower sight-feed connections, substantially as and for the purposes hereinbefore set forth.

4. The upper sight-feed connection formed with a passage for connecting the auxiliary steam-conduit and the oil-exit pipe, in cornbi nation with the sight-feed tube andthe screwvalve B2, movable toward and away from the sight-feed tube and constructed and arranged to open and close the upper end of said tube without closing said passage, as and for the purposes hereinbefore set forth.

V5. The combination of the oil-reservoir, the sight-feed tube, and its lower connection with the upper sight-feed connection provided with two independent oil-outlet passages--the one for oil from the reservoir, the other for oil from a hand-oiler-the condenser and auxiliary steam-conduit leading therefrom to said upper sightfeed connection, and the auxiliary handoiler, under the arrangement and for operation substantially as hereinbefore set forth.

6. rIlhe upper sight-feed connection provided with passage nza, by-passage n', neck n3, oiler H, and valve B, in combinationwith the sight feed tube and its lower connection, the oil-reservoir,the condenser, and the auxiliary steamconduit, as and for the purposes hereinbefore set forth.

In testimony whereof I have hereunto set my hand this 15th day of October, 1886.
